Lamp unit using short-wave light emitting device

A short-wave light emitting diode lamp unit comprising:

• a housing having an opening;
• a printed circuit board on which electronic parts are mountable, the printed circuit board being disposed inside the housing;
• a plurality of short-wave light emitting diode chips mounted on the printed circuit board so that a light emission side of the short-wave light emitting diode chip faces the opening of the housing;
• and
• a light transmitting plate attached to the opening of the housing, the light transmitting plate being made of a glass material having high ultraviolet ray transmittance of about 80% or more for ultraviolet rays having a peak wavelength of about 380 nm.
